Gallium nitride technology is used for the higher frequencies in 5G chips. Currently only suppliers outside of China produce such chips.

From a business perspective, pushing 5G as fast as it is pushed now by China, does not make sense. Chinese network operators would not want to deploy 5G quite as fast as they are being forced to, but China’s government is imposing it.

So why impose it? There might be several reasons, e.g. to have a dominant position in setting industry standards, but one reason stands out: The complex 5G standard requires frequent software that make it harder to enforce security software reviews and anti-espionage measures.
